Things You'll Need:

Access to a Mac OS Tiger upgrade
Mac OS Tiger

Step 1

Be aware that in order to upgrade to Mac OS Tiger, you have to be running an earlier version of the Mac OS, like Max OS 9 or Mac OS Panther. An upgrade from Mac OS Tiger to Mac OS Tiger would be an update.
Step 2

Start your Mac as you normally would and log in using the system administrator account. If you are the sole user of the Mac, your account is the system administrator by default.
Step 3

Acquire the upgrade either by purchasing it online from the Apple Online store or by picking up an upgrade copy from an actual retail outlet (see Resources below).
Step 4

Start the upgrade process using the medium you've purchased. For example, place the DVD into the DVD drive if you bought a hard copy from the Apple Store, or simply run the downloaded file from your hard drive.
Step 5

Choose the options and preferences in the installation process that you want to use in the upgrade to Mac OS Tiger.
Step 6

Follow the onscreen prompts during installation.
Step 7

Restart your computer once the upgrade is complete.

Tips & Warnings

Keep informed about when a new upgrade is going to become available. Apple's mailing list will tell you when the next major upgrade to Mac OS is coming.
Be aware that an update and an upgrade are two different things when discussing a Mac OS. An update is an incremental patch to a specific operating system, while an upgrade is a shift to an entirely new version of the Mac operating system platform. Updates can generally be downloaded for free.
Always back up your files whenever you choose to upgrade Mac OS Tiger just to be on the safe side. The likelihood of a major failure is very small, but it can happen. Copy your files to an external hard drive or burn them to a CD or DVD.
It is not free to upgrade your Mac OS. Each new version of the operating system needs to be purchased separately.
